Bourns 1.85 A Resettable Fuse 30V Radial Leaded Epoxy Polymer MF-R185

Bourns MF-R185 resettable fuse is a radial leaded circuit protection device with a hold current of 1.85 A and voltage rating of 30 V. It prevents damage to electrical and electronic circuits by automatically switching from a low resistance state to a high resistance state when an overload or short circuit occurs.

Constructed with a cured, flame retardant epoxy polymer insulating material, this fuse meets UL 94V-0 standards, assuring safety and durability in harsh conditions. Its compact dimensions of 12 mm length, 18.4 mm height, and 3 mm width make it suitable for PCB mounting without requiring a fuse holder, saving space in designs.

The device features radial lead orientation with 0.51 mm diameter leads designed for easy and reliable PCB soldering. It supports a high current rating of 40 A with a rapid trip time of 8.7 seconds under a trip current of 3.7 A. The minimum resistance is 0.04 Ω and maximum resistance is 110 mΩ, contributing to efficient circuit protection with minimal loss.

This Resettable Fuse operates effectively in a wide temperature range from -40°C to 85°C, making it adaptable to various industrial, commercial, and medical applications. Its power dissipation rating of 1 W ensures stable performance during load conditions.

Certified to RoHS and UL standards, the MF-R185 fuse is suitable for protecting power supplies, transformers, automotive electronics, medical equipment, security systems, instrumentation, control circuits, computers, and audiovisual telecommunications equipment.
